AZ-800 Azure Route Tables and User-Defined Routes 2

Question 1

What does the 'BGP route propagation' setting on an Azure subnet control?

Accepted Answer

Whether routes learned from a VPN or ExpressRoute gateway are automatically added to the subnet's route table

Answer

Disabling BGP route propagation on a subnet prevents routes learned from VPN or ExpressRoute gateways from being automatically injected into that subnet's effective routes.

Question 2

To implement forced tunneling (routing all internet traffic through on-premises), which UDR configuration is required?

Accepted Answer

A route for 0.0.0.0/0 with next hop type VirtualNetworkGateway

Answer

Forced tunneling uses a default route (0.0.0.0/0) with VirtualNetworkGateway as the next hop to redirect all internet-bound traffic through the on-premises VPN gateway.

Question 3

What is the maximum number of routes allowed per Azure route table?

Accepted Answer

400

Answer

Azure route tables support a maximum of 400 routes per table, as documented in Azure's subscription limits and quotas.

Question 4

Which Azure service provides the 'Effective Routes' feature to view all routes applied to a specific network interface?

Accepted Answer

Network Watcher

Answer

Azure Network Watcher provides the Effective Routes feature, displaying all system routes and UDRs currently applied to a network interface.

Question 5

When VNet peering is established, what system routes are automatically added?

Accepted Answer

Routes for the peered VNet's address space with next hop type VirtualNetwork
